Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Tomatoes
- Provide the main body and fresh, juicy base of the salad.
- Egg yolks
- Emulsify and thicken the dressing, giving it a creamy, rich body.
- Mustard
- Adds sharp, tangy flavour that balances the sweetness and richness of the dressing.
- Tomato juice
- Supplies moisture and liquid body to the dressing.
- Vinegar
- Adds acidity, giving the dressing its sour bite.
The step that matters
Add the vinegar gradually. Acid can thin and curdle an egg-based dressing if overdone, and its sharpness intensifies as it sits. Adding it a little at a time and tasting lets you reach the desired sourness without making the dressing harsh or watery.
Flavor stand-ins for the celery

Fit is the average pairing score against tomato, egg, mustard, pepper, sugar, vinegar. Candidates are from the same food group and used in at least 100 recipes. This compares flavor only: it does not check the job the ingredient does in the dish (bulk, moisture, acidity, structure).
